Storage library systems are often used by enterprises and the like to efficiently store and retrieve data from storage media. In the case of some storage libraries, the media are data cartridges (e.g., tape cartridges) that are typically stored and indexed within a set of magazines. When particular data is requested, a specialized robotic mechanism finds the appropriate cartridge, removes the cartridge from its magazine, and carries the cartridge to a drive that is designed to receive the cartridge and read its contents. Some storage libraries have multiple drives that can operate concurrently to perform input/output (10) operations on multiple cartridges.
Ensuring proper functioning of the storage library involves secure and accurate positioning of components, including magazines. Further, various functions involve accurate positioning of the robotic mechanism in context of the magazines and other components. To this end, traditional implementations often include a variety of sensors, targets, and the like, which can add cost and complexity.
